996 Convertible Top Light

[Sand996]

I changed the hydraulic cylinder for the convertible top on the passenger side of my 996. Now the convertible top light on the dash wont go off. The top cycles perfectly and the fluid is at the correct level. I've used my durametric software and can't access the instrument panel due the the year of the car ( 1999 ). The top will go up and down just fine and once the cycle is complete the dash light will flash but not go off. The windows go down when I put the top down but do not go up when I close the top.

The light worked fine before I changed the hydraulic cylinder so it must have something to do with that.

I'm lost!

Try a soft reset by disconnecting the battery..make sure you have your radio code....

Thanks for the help but I've tried that as well.

That signal gets sent from the Convertible top control unit so you might check disconnected or damaged microswitches.

Also, did you recalibrate the top?

[Sand996]

Sorry, I don't know what it means to recalibrate the top. Can you elaborate please?

[Loren]

I do not not if the Durametric software has that option in the convertible top controller or not. The PST2 and PIWIS do have the option.

It takes the top and slowly runs it through it's full retraction and extended positions and reset the limits for the microswitches. Whenever any parts are changed on the convertible top is recommended to re-calibrate the top.

I'll look into it. Thanks for the help.

According to the Durametric website the latest version of the software will recalibrate the top. However, I don't know if you need the "professional" version or if the "enthusiast" version will do this. I have read that the enthusiast version will not do coding.

From the Durametric website:

"

Second release of Durametric 6.0

* Added Coverage for 996 and Boxster (986)

* Many new features that are not available in Durametric 5. Here are some examples:

o Enabling and disabling the On Board Computer (OBC). Even though this is technically "coding," it is included in both the Enthusiast and Professional kits

o Clearing fault codes on Alarm, along with other alarm features like activations and input signals

o Brake bleeding

o Convertible top calibration on 996 Cabriolet

o Activations on most modules

o Coverage for every possible control module on Boxster and 996. New for version 6.0: Litronic headlight control(HBA), Roll-over protection, Park assist, and Targa control modules

o Coding on some modules

o Actual values on more modules

o And much more..."

I'll check which version I have. I've only had it for a couple of months so hopefully it's the newest. Great info. Thank you.

OK. I ran the calibration on the top (using the Durametrics software) and it put the top down but then stopped. It apparently couldn't do anything else. The Top wouldn't go back up and finish the calibration.

I then clicked "check" fault codes and then clicked "clear" fault codes. The message on both attempts was "unable to communicate to this module". I can only assume that some sort of fuse/module is malfunctioning.

Any tips at this point????

Thanks for all the help.
